Chain Link: Load Capacity 5-200 kg/m, Width 30-600 mm

Component Specifications

Definition

A chain link is a standardized mechanical component used in cable and hose carrier assemblies to create articulated, flexible tracks that guide and protect cables, hoses, and pneumatic lines in automated machinery. These links interlock to form continuous chains that move along predetermined paths, preventing tangling, abrasion, and stress on utilities during repeated motion cycles. They are engineered to maintain precise alignment while accommodating multi-axis movement in industrial applications.

Working Principle

Chain links operate on the principle of articulated joint connections that allow rotational movement while maintaining structural integrity. Each link connects to adjacent links via pivot points or hinge mechanisms, creating a flexible yet rigid track. When installed in carrier systems, these links form a protective enclosure that moves synchronously with machinery components, ensuring cables and hoses follow optimal bending radii and avoid sharp kinks or excessive tension.

Materials

Typically manufactured from engineering-grade thermoplastics (POM, PA6, PA66 with glass fiber reinforcement) or metals (stainless steel, aluminum alloys, galvanized steel). Material selection depends on application requirements including load capacity, environmental resistance (chemicals, temperature, UV), and required flexibility.

Frequently Asked Questions

What is the difference between plastic and metal chain links?

Plastic chain links offer lighter weight, corrosion resistance, and quieter operation, ideal for clean environments and moderate loads. Metal chain links provide higher strength, better heat resistance, and durability in harsh industrial conditions with heavy loads or abrasive environments.

How do I determine the correct bending radius for chain links?

The bending radius should be at least 10 times the diameter of the largest cable or hose being protected. Always follow manufacturer specifications and consider factors like cable type, movement speed, and expected service life to prevent premature failure.

Can chain links be used in high-temperature applications?

Yes, specialized chain links made from high-temperature thermoplastics (PEEK, PPS) or metals can withstand temperatures up to 250°C. Always verify material specifications and consider thermal expansion effects on performance.
